   | CuPHC EN: CW020A UNS: C10300 |    |
Cu-PHC combines good electrical conductivity with excellent hot and cold fabricability and joining characteristics (welding and brazing). C10300 has 99% IACS electrical conductivity, excellent hot and cold workability. C10300 is not hardenable by heat treatment. It may be joined by gas shielded arc with excellent results. Soldering and brazing performance is also excellent. Butt resistance welding is good and oxyacetylene weldability, fair. Common fabrication processes include: blanking, coining, coppers mithing, drawing, etching, forming and bending, heading and upsetting, hot forging and pressing, piercing and punching, roll threading and knurling, shearing, spinning, squeezing and swaging, stamping.
